SPINNING-SPINDLE.`

SPECIFICATIQN forming part of Letters Patent N0. 671,694, dated April 9,1901. Application filed October 22,1900. Serial No. 33,806. (N0 mOdeL) iTo t/Z whom, t may concern:

Be it known that we, WILLIAM H. GOLD- SMITH and STEPHEN M. HAMBLIN,citizens of the United States, residing at Central Falls, in the countyof Providence, State of Rhode 4Island,have invented a certain new anduseful Improvement in Spinniug-Spindles, of which the followingisaspecicatiomreference being had therein to the accompanying drawings.

Figure l of the drawings shows, partly in elevation and partly insection, an embodiment of our invention. Figs. 2 to 5 showmodifications.

Our invention consists, mainly, in forming a spinning-spindle in twoparts, one of such parts, termed by us the whi rl part, being providedin practice with a suitable bearing in a spinning-frame and remainingpermanently associated with the said bearing in the 'saidspinning-frame, and the other of such parts bein termed the skewer itbeingin the shape of a detachable spindle-blade and being adapted to beapplied to and connected with the whirl part to rotate in unison withthe latter during the spinning operation and to receivethe yarn load,the said skewer be- -ing adapted to be detached from the whirl partafter having been fully loaded with yarn, it being especiallyconstructed with reference to enabling it to be placed directly into ashuttle for weaving the said detachable skewer, taking in the shuttlethe place of the usual spindle, which last is dispensed with.

Having reference to the drawings, l designates the whirl part of ourimproved spindle. The whirl thereof is designated 2. The said whirl part1 is or may be in 4practice constructed like the whirl and lower orbearing part of any of the approved makesof spindles. Herein it is shownconstructed with a downwardly-extending cylindrical foot p0rtion 3 belowthe whirl 2, corresponding substantially in shape with the foot portionsof spindles now in use, the said foot portion 3 being fitted within anexternal bearing 4 in a bearing-support 5, the said bearing-supportbeing secured in a hole of the spindle-rail 6 by means of a nut 7 uponthe threaded lower end 8 of the said bearing-support in customarymanner. 9 designates the usual hook or detent for preventing the whirlpart l from becoming accidentally lifted out of the hearing of thebearing-support. The said whirl part l is made hollow or tubular to forman elongated cylindrical central chamber to receive the lower end of theskewer l0. The said skewer mayin practice be formed of any suitablematerial, but preferably is made of Awood for the sake of cheapness andof lightness,which last is of especial importance when the skewer, withits load of yarn, is placed in a shuttle in order that the said load ofyarn may be utilized as weft in Weaving cloth.` The shape of theinterengaging portions of the whirl part and skewer may be varied moreor less, although preferably we form a tapering bore ll within the whirlpart and correspoudingly taper the portion l2 of the skewer which entersthe said bore. The fit of the end of the skewer within the bore of thewhirl part secures the requisite frictioual adhesion for causing theskewer to rotate in unison with the whirl part during the operation ofspinning. If desired, we may increase the said frictional adhesion byslitting the end of the skewer, as at 14 in Fig. 2, in which case theelasticity of the portions of the skewer end which are separated by theslit will be brought into play by the compression which occurs when theskewer end is forced home into the bore of the whirl part. In this casethe skewerend will be made a little larger relatively to the diameter ofthe bore of the whirl part, so as to insure the bending of the saidparts of the skewer end toward each other as the skewer end-is caused toenter the bore of the whirl part. When the skewer end is slitted, asjust described, the said skewer end need not be tapered and may be leftcylindrical, as shown in Fig. 2.

In some cases we may provide a positive lock for compelling the skewerto rotate in unison with the whirl part. Thus in Fig. 3 we have shown awire or screw 15, driven across the inner part of the bore of the whirlpart, the end of the skewer being notched, as at 16, to t over the saidwire or screw. The fiat side ofthe notch fits against the side of thesaid wire or screw.

In some cases we may employ a yielding clip or pressure device toprevent the skewer from rising within the whirl part and becoming IOOloose with reference thereto. Thus in Figif we have shownasplit ringl7,.seated within an internal groove 18, formed in the whirl part. Whenthe skewer end is pushed into the bore of the Whirl part, it preferablyexpands the said split ring which clamps the skewer end firmly. Thisdevice prevents the skewer from coming loose at high speeds of`rotation.

Fig.` 5 shows a form of the invention in which thewhirl part is providedabove the whirl with an` extension 19, which is slitted, as at 20, toform a series of elastic tongues. The series of elastic tonguesconstitute a yieldingclamp to hold the skewer in place.

Preferably we form the skewer double ended, as in Fig. l-that is to say,it is symmetrical, both ends being alike, so thateither end may beentered indifferently into the whirl part, according as the skewer mayhappen to be picked up for the purpose of being applied to the Whirlpart. The skewer is slightly barrel shape-that is to say, is largestin'diameter at about mid-length thereof and gradually contracts indiameter therefromvto the entering ends. The barrel shape of the skewereliminates tendency of the same to warp, kwhile the double-endedconstruction eX- fined in the whirl part to escape as the skewer isbeing inserted into the bore of the latter and pressed home, We form agroove leading to the outer end of said bore in the inner surface of thesaid whirl part. This groove either mayextend straight along said bore,as -at 24, Fig. 4, or spirally, as at 25, Fig. 5. The -escape of .theair which is permitted by the said groove obviates tendency of theskewer to become forced upward and loosened inits seat within the whirlpart by expansion of said air when the Whirl part becomes warm inoperation.

We claim as our inventionl. rIn combination, in a spinning-machine, thewhirl part havinga downwardly-extending cylindrical Aportion containinganfelongated cylindrical central chamber, an external bearing receivingthe said cylindrical portion, and the skewer on which the yarn isreceived as spun, detachably tting at its lower end Within the centralchamber of the said Whirl part for the spinning operation and adapted tobe removed therefrom with its load of yarn, substantially as described.

2. In combination, in aspinning-machine, the rotating whirl part, thebearing in which the said whirl part is-permanently mounted, and thewooden skewer on which the yarn is received as spun applied to the saidwhirl part during the spinning operation, and adapted to `be detachedtherefrom when the said yarn load, has been completed, substantially asdescribed.

3. In combination, in a spinning-machine, the rotating Whirl part, abearing with which the said whirl part remains permanently connected,and the double-ended or reversible skewer on which the yarn is receivedas spun connected with the said rotating whirlpart during theoperationof spinning and adapted to be detached therefrom when its yarnload is completed, substantially as described.

4. In combination, in a spinning-machine, therotating Whirl part havingthe internal boreand the groove forming a vent for air, and the skeweron which the yarn is received as spun tting Within the said bore anddetached therefrom when the load of yarn has been completed,substantially as described.

5. A solid yarn-skewer for spinning, e., having the main length thereofshaped to contain a load of yarn wound thereon in the spinningoperation, and having the end thereof shaped to enter and Iit detachablythe socket of a rotating Whirl,substantially as described.

6. A solid reversible yarn-skewer for spinning, dac., having the mainlength thereof shaped to contain a load of yarn wound thereon in thespinning operation, and having each end thereof shaped to enter and fitthe socket of a rotating w'hirl,snbstantially as described.

7. Ayarn-.skewer for spinning, dac., having thebarrel-shaped body tocontain a load of yarn Wound thereon in the spinning operation, andhaving each end thereof shaped to enter and fitthe socket Vof arotatingwhirl, substantially as described.

In testimony whereof we affix our signatures in presence of twoWitnesses.
